Patented Jan. 22, 1901* v Application filed June 23,1905. Serial No 266,611.-

To (ZZZ whom-it mag concern:

Be it known that I, VVILiLIAM G. ROWELIJ,

a citizen of the United States,' residing at Bridgeport, in the county of.Fairfie ld and State of Connecticut, have invented certain new and useful In! rovements in ,VVater-Faucets; and I do here y declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in-the art to which it appertains to make and use the same.

My invention relates to water-faucets; and

it consists in certain details of construction and combination of parts hereinafter fully set forth, and specifically designated by the "claim.

In the accompanying drawings, Figures 1 g and 2 are sectional elevations of my improved faucet, respectively showing the shank is also cored so as to leave a passage 6,

which has no communication with the chamher 4 or assa e 5 exce t throu h the o )enin P g g e l g 7 in the horizontallyisposed floor 8 of the body 1. This body 1 is threaded interiorly at its upper end, and a cap 9, having a thread ed plug 10 and an annular shoulder 11, is

driven within this body until the shoulder 11 impinges against the top of said body.

A recess 12 extends from the bottom of the i plug up into the body of the cap, and an openrecess. four separate female threads (1 b c d, each of ing 13 extends from the top of the cap into said recess. Both this opening 13 and recess 12 are circular in cross-section, the diameter of the recess being greater than the diameter of the opening, so that an annular shoulder 14 is formed at the upper end of said Within the wall of this recess are out which completes the circuit of said wall from a point at the top of said wall to apoint at the bottom thereof. a

Through the opening 13. extends the valvespindle 15, and 16 is a g land surrounding the spindle and driven on the top of the cap- 9 .and'inclosingany suitable packing 17. fThis spindle carries four separate male threads, 8 fg h, which engage the female threadsa b c (i, so that it will 'be clear that when the spindle it turned slightly its lengthwise movement will be considerable. The-bottom of the spindle has a. socket 18 formed therein, into which the stem 19 of the valve 20 fits loosely.

The depth of the socket is greater than the length of the .stem. Both socket and. stem are circular in cross-section, and the socket is provided with a vent 21 at its inner end, so that the valve can always have free play when the spindle is elevated, as will be presently explained. 1

Stem 19 is'formed at its base with an en- 'larged part tapered on its upper face, it being noted that when valve 20 is raised by the pressure of water and is rotated by the water the tapered portion of the valve will be subjected to equal wear throughout its bearingface with respect to the lowerededge ofthe valve-spindle.

Around the top of. the opening 7 is formed a valve-seat 22, so that it will be clear that when the valve 20 is driven against said seat the water will be shut off, and when .the spindie is elevated the force of the water will raise the valve to allow the water to flow out through the nozzle.

Surmounting the spindle is any suitable handle 23, and by giving this a quarter-turn in one direction the valve can be fully opened, while a quarter-turn in. the reverse direction will completely close the valve.

By providing four separate threads, as above set forth, I am enabled to obtain an end thrust of the spindle on a quarter-turn thereof as great as a similar thrust produced by a full turn of the spindle with a continuous threaded connection.

This is a great advantage in water-faucets of the compres I sion type, since the leakage is reduced to a minimum and the operation is rendered ex ceedingly'rapi'd. i

The valve-stem fits loosely within the Socket at the bottom of the stem, and since,

this socket hasa vent at the top the eleva tion of the valve-stem and the; consequent through the faucet coming in contact with sudden flow of the water withfull force the valve will cause the valveto be rotated,

so that the seating. surface of the valve will be constantly. changed withrespect to the valve-seat, thus preventing undue wear upon any portionofthe seat oiwalva- :Moreover,

j this quick operation of the faucet by means of the four separate threads, as above set forth, prevents any hammering, such as is occasioned'by the force of the water in the instance of com ression-faucets that are opened and clos d by the operation of a slow screw. I

The upward movement -of the valve is checked by the abutment of the upper ends of the male threads on-the valve-stem against the ShOllldBP'lfI, whilethe'valve-seat itself "arrests the downward movement of the valve;

' Having thus describedmy invention, what I claim as new, and desire to secure by Letters Patent, is- H g In a faucet, the-combination of a body portionhaving an interiorly-threaded upper pletes the circuit of the wall from a point at the top of the wall to -a point at the bottom thereof, said valvc spindle being formed with like threads of the same number correspending in pitch thereto, said valve-spindle having a portionthereof projecting beyond said threads and having a socket formed in its bottom and-a side vent-at a point directly at the top of said socket, a valve-stem extending in said socket having free rotar and vertical movement therein, and 0 less length than said socket, an enlarged base on said valve-stem having a tapered upper face,

a removable valve rigidly secured to the under face of saidbase, and a-handle for rotating said sfpindle, said cap-shoulder at the junction 0 the recess and o ening restricting said spindle in its upward movement to a quarter-turn, and said valve-seat likewise restricting said spindle in its downward course to a quarter-turn, said valve-stem being of greater length than the greatest movement of said valve-spindle resulting from a quarter-turn thereof, said valve being raised by the ressure of water when said valve spindle is raised and being rotated by the action of the water whereby said tapered, face of the valve will be subjected to equal wear throughout its bearing-face with respect to the lower edge of said valve-spindle.

In testimony w'hereofI afiix my signature in presence of two witnesses.
